Frequency setting by external terminals
REMARKS
During jog operation or PID control operation, the remote setting function is invalid.
CAUTION
When selecting this function, re-set the maximum frequency according to the machine.
Parameters referred to
Pr. 1 Maximum frequency, Pr. 18 High speed maximum frequency Refer to page 78
Pr. 7 Acceleration time, Pr. 8 Deceleration time, Pr. 44 Second acceleration/deceleration time, Pr. 45 Second deceleration time Refer to page 91
Pr. 178 to Pr. 182 (input terminal function selection) Refer to page 108
Setting frequency is "0"
Even when the remotely-set
frequency is cleared by turning on
the RL (clear) signal after turn off
(on) of both the RH and RM
signals, the inverter operates at
the remotely-set frequency stored
in the last operation if power is
reapplied before one minute has
elapsed since turn off (on) of both
the RH and RM signals
When the remotely-set frequency
is cleared by turning on the RL
(clear) signal after turn off (on) of
both the RH and RM signals, the
inverter operates at the frequency
in the remotely-set frequency
cleared state if power is reapplied
after one minute has elapsed
since turn off (on) of both the RH
and RM signals.
